Sam Shuster Department of Dermatology, University of Newcastle, Newcastle upon Tyne, UKAbstract: The continued discussion about the meaning of Camus’s famous novel, L’étranger, provoked a re-reading, and this, in turn, led to its clinical analysis and further investigation. The book rests entirely on the thoughts, words and actions of its central character, Meursault, and these were found to show impairment of social relationships, communication and interaction, with other traits diagnostic of the Asperger’s subgroup of the autism spectrum disorder. It was then found that Camus had based Meursault on his close friend Galindo, and a search was therefore made for evidence of Galindo’s character; this revealed him to be an intelligent but odd person, who exhibited the characteristic impairment of social and personal behavior of Asperger’s syndrome. Thus, Camus had recognized and understood his friend’s strange behavior before Asperger’s syndrome had been defined; his use of it for the creation of Meursault is therefore the first published account of a man with this disorder. Many of the interpretations and ideas developed from Meursault’s words, thoughts and actions must now be reconsidered, as they are a misreading of the words and behavior of a man with Asperger’s syndrome. The outcome of this clinical examination of L’étranger is unique; it shows that a precise account of a person with a neurobehavioral disorder was made by a novelist before the disorder had been clinically defined.Keywords: Asperger’s syndrome, Camus, Meursault, L’étranger

Sam ShusterNewcastle University, Newcastle Upon Type, NE1 7RU, UKAbstract: The response to seeing a man riding a unicycle was reported to be consistently related to the viewer's sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15–69 years, with 2–40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection.Keywords: humor evolution, male aggressive behavior

The apparent intensity of hyaluronan (HA) staining in tissue sections can vary as a function of fixation techniques. We examined the histochemical distribution of HA in normal human skin using an HA-specific binding peptide derived from bovine nasal cartilage. The HA, particularly in the dermis, was best preserved in sections fixed in 10% acid-formalin with 70% ethanol. In contrast, sections fixed in the routine 10% neutral-buffered formalin had a much weaker intensity of HA staining. Furthermore, acid-formalin/ethanol-fixed sections retained much of their apparent HA after incubation with saline, in contrast to the neutral formalin-fixed sections, in which most of the stainable HA was lost. Such marked differences in staining intensity were not observed in slides stained with Alcian blue, a procedure presumed to stain HA as well as other glycosaminoglycans. Staining using the HA binding peptide was entirely absent when sections were first preincubated in hyaluronidase, whereas similar Alcian blue-stained sections retained most of their staining intensity. Caution should be exercised in evaluating the distribution of HA in tissues using the HA binding peptide, particularly when different fixation techniques among several laboratories are being compared. In addition, the ability to evaluate the HA content of tissues using Alcian blue staining should be reconsidered. The sulfated glycosaminolglycans of the "ground substance" appear to be the predominant substrates for Alcian blue.
